CORN SHREDDER AND HUsKE'Rj Application filed February 18, 1927. Serial No. 169,301.

the final delivering conveyor also, to

provide an improved arrangement of conveyor and screen for collecting any corn which has been shelled; and to provide a booster fan arranged in novel relationship to the usual stacking fan and to the lower part of the machine wherebyit will boost or supplement the action of the main fan and will also keep the lower part of the machine free from refuse.

Other objects of the invention will appear from the following description; the novel features and combinations are set forth in the appended claims.

In the accompanying drawings:

Figure 1, is a side elevation of the complete machine, certain parts being broken away, and the different drives being omitted for the sake of clearness; and

Fig. 2, is a front elevation of the improved shuckin or husking rollers'and drum.

The frame of the machine appears at 1, being supported by the usual wheels 2. The stack is shown at 3 and the ordinary stacking fan, not shown, is contained within the chamber 4.

The final or delivering apron or conveyor which takes off the husked ears is shown at 5, being carried by a suitable frame 6 pivoted at 7 and adapted to be raised and lowered by a cable 8, operated in any suitable manner. The operator stands on a platform carried by the frame 1 and throws or places the corn on the endless apron or conveyor 9 which delivers the corn to the severing rollers 10. The rollers 10 are ribbed or corrugated in any suitable manner in the direction of their length so that they will firmly grasp the'corn stalks and squeeze off the severed ears, the latter, however, being still-encased in their husks or shucks.

To prevent clogging or congestion of the corn being fed by the apron 9 to the rollers 10, there is provided a shaft llwhich may carry as many toothed wheels 12 as may be necessary to agitate the mass of corn so that it will be properly fed to therolle'rslO. Located to the rear of the rollers 10'is the shredding or cuttingdrum or cylinder 13 which has the usual knives 14 and revolves at a high rate of speed. The stalks and leaves are cut up and shredded by the drum l3.

There is provided a bar or divider 15 between the roller 10 and the drum 13 1 This" bar causes the stalks to pass over it and it splits up the streams so that the leaves and stalks are thoroughly cut up. The shredded stalks and leaves are sucked by the fan 4' and blown through the stack 3 to be deposited at one side of the machine, in the usual manner.

Located below the conveyor 9 are inclined husking or shucking rollers 16 which have teeth l'i. There is a space 18 provided between the apron 9 and the rollers 10 through which the ears that have been squeezed off by the rollers 10 fall, passing on to the husking rollers 16.

To prevent the husking rollers from tearing up the ears, there is provided between adjacent rollers 16 the separators 18 running lengthwise of the rollers.

To prevent the ears from passing from the husking rollers 16 before the husks or shucks have been removed, there is provided a drum consisting of blades 19 provided with teeth 20, said blades being adapted to rotate above the separator strips 8. The drum beats back the ears so that they will be subject to the teeth 17 for a suflicient length of time to insure removal of the husks.

The husked ears pass on to the delivering apron 5. 1

Located below the husking rollers 16 is an apron or conveyor 21 whose purpose is to carry rearwardly any shelled corn which may have been removed from the ears by the rollers 16. The apron passes through a screen 22. The shelled cornfinally reaches the chute 23 which directs it to a trough 21 of the screen or conveyor 25 that feeds it laterally to the end of the trough, whence it is collected in a suitable sack.

Located beneath the apron 21 is a booster fan 26 operating in a shell 27 and being adapted to blow rearwardly of the machine. This fan not only clears the lower part of the machine of refuse but it also supplements the action of the fan contained within the casing at and assists in carrying oil the shredded stalks and the husks.

What I claim is:

1.111 a corn shredder and husker, the combination with rollers "for severing the stalks from the cars, and a shredder, 0t means for dividing the stalks while passing from the rollers to the shredder.

2. In a corn shredder and hnslzer, the combination with rollers for severing the stalks from the ears, and a shredder, oi't means for dividing the stalks while passing; from the rollers to the shredder, comprising a bar past which the stalks are fed by the rollers.

23. In a corn shredder and bunker, the COITlblIltltlOIl with rollers for severing stalks from the ears, of a shredder for neting on the severed stalks, means tor feeding the corn to said rollers, and a rotary agitator and feed booster arranged to art on the corn being led to the rollers.

at. In a corn shredder and husker, the combination with rotary toothed hashing rollers, of sepa 'ator or guard strips located between the adjacent rollers, and means ope 'ating above and close to the guard strips in the region of the delivery ends of said rollers for heating hack the ears While on the bushing" rollers.

In a corn shredder and hnsker, the combination with rotary toothed hashing rollers, ol separator or guard strips located be tween the adjacent rollers, and rotarily mounted heating blades operating over the respeelire separator or guard. strips in the region of the delivery ends ol said rollers and :nla'pted to heat back the ears on the rol le rs.

(i. In a rorn shredder and husker, the rombinatioi'l with rollers tor severing the cars from the stalks, a shredder, and bushing; rollers, ol an endless conveyor located beneath the shredder and the hueker, a stacking tan, and a booster tan, said con-- reyor eatcliing the shredded material and also the droppil'lgs from the huslter, said lnmster fan assisting in the stacking of the refuse and shredded material, a screen an der which the endless conveyor passes, and means under the screen for collecting; the shelled corn which may he dropped.

in tilntllllOll) whereof I atlix my signature.
